[0010] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0011] like Figure 1 As shown, the utility model discloses a device for adding CMC medicine by spiral, which is composed of twelve parts: medicine adding port 1, medicine storage barrel 2, silo wall vibrator 3, material discharge valve 4, unloader 5, screw conveying motor 6, screw conveyor 7, medicine adding pipe 8, radar material level meter 9, 1# inverter 10, 2# inverter 11, PLC industrial control cabinet 12. The functions of each component are as follows:

[0012] The medicine adding port 1 is installed on the side of the medicine storage barrel 2 and is used to add CMC medicine into the medicine storage barrel 2;

[0013] The reagent storage barrel 2, whose outer wall is made of thickened stainless steel plate and whose inner wall is coated with corrosion-resistant coating, is used to store CMC reagent added by the staff;

[0014] The silo wall vibrator 3 is installed on the side wall of the reagent storage barrel 2. The vibration frequency and vibration time are set by PLC, and the vibration is timed to solve the problem that the CMC reagent has high viscosity and is not easy to slide;

[0015] The unloading valve 4 is installed at the bottom of the reagent storage barrel 2. According to the properties of the ore in each shift, the amount of reagent entering the screw conveyor 7 is roughly adjusted by mechanical means at one time;

[0016] The discharger 5 is installed at the lower end of the discharge valve 4, and the speed of the discharge motor of the discharger is controlled by the 1# inverter 10 to achieve the purpose of secondary regulation of the amount of medicine entering the screw conveyor 7;

[0017] The screw conveying motor 6 provides power for the screw conveyor 7. The motor speed is controlled by the 2# inverter 11, and then the speed of the screw conveyor 7 is controlled, so as to achieve three-fold regulation of the amount of medicine entering the medicine adding pipe 8;

[0018] The screw conveyor 7 provides rotational power through the screw conveying variable frequency motor 6 to achieve the purpose of conveying CMC medicine;

[0019] The reagent adding pipe is installed between the screw conveyor and the ore conveyor belt.

[0020] The screw conveyor 7 delivers the reagent brought by the rotation into the reagent adding pipe 8 through the front feeding port, and then adds it to the semi-autogenous mill through the ore conveyor belt, so as to achieve the purpose of reducing magnesium oxide;

[0021] The reagent adding pipe 8 is installed between the screw conveyor and the ore conveying belt;

[0022] The radar level meter 9 is used to monitor the reagent material level in the reagent storage barrel 2. When the reagent material level reaches a certain lower limit, a voice alarm signal is sent to the computer of the engineer station in the main control room through the PLC industrial control cabinet 12 to remind the staff to add reagents to the reagent storage barrel 2 again;

[0023] 1# frequency converter 10, used to control the motor speed of the discharger unloading motor;

[0024] 2# frequency converter 11, used to control the speed of the screw conveying motor 6, and further control the speed of the screw conveyor 7;

[0025] The PLC industrial control cabinet 12 controls the vibration frequency and vibration time of the vibration motor 3 through the PLC program, and controls the start and stop and frequency of the discharger 5, the screw conveying frequency conversion motor 6, the 1# frequency converter 10, and the 2# frequency converter 11.

[0026] The working process of the utility model is as follows:

[0027] The personnel on duty add a sufficient amount of CMC agent to the agent storage barrel 2 through the agent addition port 1, and according to the production process requirements, roughly adjust the discharge valve 4 to control the amount of agent entering the screw conveyor 7; at the same time, the personnel at the engineer station in the main control room complete the following tasks: (1) Control the vibration frequency and vibration time of the vibration motor 3 through the PLC industrial control cabinet 12 to increase the agent discharge speed; (2) The discharger 5 remotely controls the motor frequency through the 1# inverter 10 to secondary control the amount of agent entering the screw conveyor 7; (3) The screw conveying motor 6 remotely controls the motor frequency through the 2# inverter 11 to control the speed of the screw conveyor, thereby achieving the purpose of three-time regulation of the agent amount.

[0028] When the material level meter 9 detects that the medicine inside the medicine storage barrel 2 reaches a certain lower limit, a voice alarm signal is sent to the computer of the engineer station in the main control room through the PLC industrial control cabinet 12 to remind the staff on duty to add medicine to the medicine storage barrel 2 again.

[0029] After three adjustments, the CMC reagent is finally sent to the semi-autogenous grinding mill feeding belt through the reagent adding pipe 8, so as to achieve the purpose of automatic addition of the CMC reagent through the spiral.
